~LZ##
This command sets the exact number of codes to be read during a sync period. ## = the number of codes.
For example: ~LZ02 causes a No Read condition to be set if exactly 2 bar codes are not fully decoded
during a sync interval.
This command overrides the ~LN## command if the number of codes set does not = 00. If ~LZ## is set to
~LZ00, the ~LN## command takes precedence.
~Hx
This command stores all parameters into non-volatile memory. This command should be the last command
sent after parameters are programmed via the above commands.
Mode 17 (~LV17)
A.
I/O operation
1.
System will operate in Edge Sync or Envelope sync mode
(~LX#).
2.
Sync polarity programmable
(~LP#)
3.
Use
~PR0200
for proper port initialization.
4.
Port 1 will pulse active ON for a bar code quality or data error condition.
5.
Port 2 will pulse active ON for a NO READ, partial or low % decode error condition.
6.
Port 3 will pulse active ON for a non-error condition.
7.
Port pulse times programmable.
(~PP801xxx)
8.
Pulses act like re-triggerable 1-shot logic
9.
Pushing the reset button or power re-cycle will place Ports 1, 2 and 3 in their inactive states
and reset the # codes per sync counter.
10.
Error conditions available are:
a.
Partial Read (Programmable,
( ~Lp#, LQ#)
b.
% decode (Programmable,
~LD##)
c.
Bad Quiet Zone: < 10X
(~PB816xxx100)
d.
ANSI Defects grade (Programmable,
~PB806xxx000)
e.
ANSI Decodability grade (Programmable,
~PB802xxx100)
f.
Symbol Contrast grade (Programmable,
~PB804xxx100)
g.
Overall ANSI Grade (Programmable,
~LAxx)
h.
No Read (if sync is received)
i.
Number of codes per sync programmable
(~LN##, ~LZ##)
j.
X dimension Range (Programmable
~PB811xxxyyy)
k.
Ratio (Programmable
~PB815xxx000
)
l.
Symbology modulo check digit
m.
I 2 of 5 optional Mod 10 Check Digit data error (if enabled)
n.
Data Match Error (~BC – see Operator’s Guide)
o.
Increment or Decrement data Error (~Br – see Operator’s Guide)
B.
LED Operation
1.
LED1 will turn on when Port 1 is active due to ANSI, Symbol Contrast, X dimension, ratio, mod
check or quiet zone error conditions.
2.
LED1 will flash when Port 1 is active due to a data increment or decrement error condition.
3.
LED2 will turn on when Port 2 is active due to a partial, % decode or no read error conditions.
4.
LED2 will flash when Port 1 is active due to a Data Match error condition.
5.
Flashing on indication will override a solid indication if both types of error conditions occur.
Note; Both LEDs can be on in cases where multiple bar codes are analyzed in a sync period.
